ASTM A105 Steel Flange
GNEE Corporation offers precision engineered A105 industrial flanges at cost-effective prices for a variety of piping applications.
Flange is a connection method used for connecting pipes. The specification of flange made of carbon steel material is ASTM105. There are different types of flanges based on the function such as blind flange, slip flange and orifice flange.
Forged carbon steel to ASTM A105 is a Class 1.1 material per ASME B16.5. Typically, heat treatment of Class 150 and Class 300 A105 flanges is not necessarily required. Normalized heat treated carbon steel A105 flanges are marked A105N.
Although carbon steel is prone to corrosion, A105 flanges can be protected with coatings or linings to enhance their resistance to corrosive
environments. The high strength of carbon steel makes A105 flanges strong and reliable. A105 high temperature flanges are ideal for high temperatures and Power plants and petrochemical industries where high-pressure conditions are common.
